Hi.
I first want to tell you that I'm new to the linux environment and just started learning linux. To help you understand my problem I am giving you the configuration of my machine...
There is a command line utility called top the will show what process(es) is using all the CPU. I am sure there are GUI utilities that do the same, but I am not familiar with them
To run top just type that word into a terminal. But you might want to review its man(ual) page first. To do that, type:
First, let me give you a tip about posting computer output (and code/script listings, etc): wrap it in code tags. This will cause everything to line up like it was on your computer screen. A little while back I did a whole post on this which you can view here. It includes instructions on how to do it.

Your culprits are kacpid and kacpi-notify which are using 73% and 20% of (an individual processor's) time respectively. I don't have the time to really dig into this right now, but I think these are both kernel threads that have something to do with ACPI. A quick search turned up other threads that might be related here, here, and here Maybe reading those and/or some more searching might give you some clues, or maybe somebody else can post more about this issue.
